A receptacle may receive projectiles and includes a pipe engageable into the projectile feeding tube, and a control ferrule includes an inner thread for threading with the outer thread of the projectile feeding tube, and for detachably securing the pipe of the receptacle to the projectile feeding tube, and for allowing the pipes of the receptacles of various sizes or outer diameters may be changeably engaged into the projectile feeding tube, and selectively secured to the projectile feeding tube.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a compressed gas gun or a paint bullet gun, and more particularly to a compressed gas gun having an improved projectile feeding tube for attaching magazines or receptacles of various shapes or sizes or diameters thereto.

2. Description of the Prior Art

Typical compressed gas guns comprise a gun body, a stock, a trigger, a bullet loading guide, and a sight rack, in which the bullet loading guide is secured onto the upper gun barrel, for supplying projectiles or bullets into the gun barrel one at a time. Normally, a compressed air reservoir is coupled to the stock or handle portion of the gas gun, for supplying compressed air to force or to shoot the projectiles or bullets out of the gun barrel.

For example, U.S. Pat. No. 6,347,622 to Hsueh discloses one of the typical compressed gas guns comprising an upper gun barrel provided on top of a gun body, and one or more bullet loading guides selectively attachable to the gun barrel. For example, the receptacle provided on the bullet loading guide may be perpendicularly extended up from the bullet loading guide, or may be obliquely extended from the bullet loading guide at 45° angle or elevation.

However, the receptacles are solidly fixed and provided on the bullet loading guide, and may not be changed to different diameters, such that the magazines or receptacles, for receiving paint bullets or projectiles therein, that have various shapes or sizes or diameters may not be suitably attached to the bullet loading guide.

U.S. Pat. No. 6,408,836 to Ming-Hsien discloses another typical compressed gas gun comprising an upper gun barrel provided on top of a gun body, and a bullet feeding device detachably or selectively attachable to the gun barrel. However, similarly, the feeding tubes of the bullet feeding device are also solidly fixed and provided on the bullet feeding device, and may not be changed to different diameters, such that the magazines or receptacles, for receiving paint bullets or projectiles therein, that have various shapes or sizes or diameters also may not be suitably attached to the bullet feeding device.

U.S. Pat. No. 6,553,983 to Li discloses a further typical compressed gas gun comprising an upper gun barrel provided on top of a gun body, and a ball feeding tube solidly provided and fixed or attached to the gun barrel. However, similarly, the ball feeding tube is also solidly fixed and provided on the gun body or the gun barrel, and may not be changed to different diameters, such that the magazines or receptacles, for receiving paint bullets or projectiles therein, that have various shapes or sizes or diameters also may not be suitably attached to the bullet feeding device.

The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional compressed gas guns.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and initially to FIG. a compressed gas gun 1 in accordance with the present invention comprises a gun body or housing 10, a gun barrel 11 formed or provided on top or in front of the housing 10, a stock or handle portion 12 provided or attached to bottom of the housing 10, and having a trigger 13 for triggering or operating the gas gun 1.

The housing 10 includes a port or coupler 20 coupled to a hose 21, for coupling to a compressed air reservoir, such as a compressed air tank 22 which may supply compressed air into the inner chamber 14 of the housing 10 or the gun barrel 11 (FIG. 3), in order to force or to shoot the projectiles or bullets out of the gun barrel 11. The above-described structure is typical and will not be described in further details.

The housing 10 further includes an opening 15 formed and provided on top of the housing 10 or the gun barrel 11 (FIG. 3), and defined by two lower side flanges 16, and two end or a front edge 17 and a rear edge 17, it is preferable that each of the end or front and rear edges 17 includes a notch 18 formed therein, also best shown in FIG. 3.

A projectile feeding tube 30 includes a lower portion 31 engaged or seated within the opening 15 of the housing 10 or the gun barrel 11, and engageable with the side flanges 16 and the end or front and rear edges 17 of the housing 10, and includes one or more, such as two projections 32 extended from the lower portion 31 thereof, for engaging into the notches 18 of the end or front and rear edges 17 of the housing 10 or the gun barrel 11, and secured to the housing 10 or the gun barrel 11 with one or more fasteners 19 or latches or the like.
